Re: I Will the point of impact change?
It might change a little due to the temperature change. I'd find what shoots best now, then check right before the season. Better yet, just keep practicing occasionally the whole time. Your point of impact can change simply by wearing different clothes. If you're wearing bulkier clothes than you practiced with, you will hold the rifle different. Good luck.
If you're having trouble hunting for deer,
don't wish things were easier;
wish you were smarter.
